Attending: Brian L, Carl, Derek, Marco, Mat, Tim T

Announcements¶

GSI Transition
- AI (Carl): will Gratia ignore SciTokens-based pilots?
- AI (Carl): HTCondor-CE Gratia probe should avoid use of condor_ce_q
XRootD in 3.6
- Need to document native VOMS and SciTokens auth. Upstream docs? SciTokens
- osg-xrootd needs to be updated (at least removing LCMAPS + config)
- Topology changes probably need to be made to also support the new format
Any new sites/CEs should be directed to the "Campus Facilitation" FD group

HTCondor service startup tests in osg-test for 9.0.1 need updates to work with new upstream configuration.
XRootD-TPC tests should be split into single-stream and multi-stream.
GlideinWMS:
- GlideinWMS 3.7.4rc1 now available; fixes a regression with 3.6 frontend compatibility.
- OSG Scitokens patches, X509-less submission, and CVMFSEXEC will go into 3.7.5. 3.7.5 expected in a month and a half. Redmine currently locked down to people with service accounts. Some issues can be tracked in GitHub. Future authentication policy has not been decided yet.

(Mat) Justas at CalTech is having STARTD_CRON issues; investigating with help from the HTCondor developers.
(Derek) ORNL is running a patched slurm gratia probe. We should engage with them to run a production probe, if we can. But their use case complicates things.

GRACC ITB Collector k8s on Tiger Jira
XRootD Multiuser: One more comment from Andy, so there will be a 1.0.1 (sorry)
- Known not to work with xrootd async io. But that might be ok.
StashCP go client is working, just waiting on effort from Derek on how to package / deliver it. As a reminder, compiling on EL7 makes it work on EL7, 8, ubuntu... Go is great!
XRootD accounting information (from Frank):
- May need help with automating the process of generating these reports. A month only takes a few minutes. Longer periods take much longer.
- Table of working set, read, and re-read for monthly, quarterly, and year.
